Is this normal?

Hi mommies my baby is 11 days old today and I noticed he’s been sleeping ALOT. Only started tracking 5 days ago and noticed he’s sleeping more thn 20 hrs a day is this normal? And he does wake up for feed but will go back to sleep right after…. Or sometimes he doesn’t wake up at all and I have to wake him up for feeds. I thought it was normal till I googled now I’m quite unsure. also should I start increasing his formula? Currently drinking 60 ml he can finish the whole bottle and still b hungry.( feeding him both fomula & breastmilk) and does anyone actually use the tracking features on this app? Is it better or other tracking apps better? Sorry for asking so many questions 🙂‍↕️🙂‍↕️But I’m Js unsure!!!! #FTM
